We consider a constrained shortest path problem with the possibility to refill the resource at certain nodes. This problem is motivated by routing electric vehicles with a comparatively short cruising range due to the limited battery capacity. Thus, for longer distances the battery has to be recharged on the way. Furthermore, electric vehicles can recuperate energy during downhill drive. We ext...

This paper explained about switching losses in prescribed circuit. Batteries are the primary energystorage devices in ground vehicles. Now-a-days battery fed electric drives are commonly being used for electric vehicles Applications, due to various advantages, such as nearly zero emission, guaranteed load levelling, good transient operation and energy recovery during braking operation. To full ...

Electric vehicles are by many seen as the cars of the future as they are high efficient, produces no local pollution, are silent, and can be used for power regulation by the grid operator. However, electric vehicles still have critical issues which need to be solved. The three main challenges are limited driving range, long charging time, and high cost. The three main challenges are all related...

This paper discusses about the potential need for electric vehicles (EV), charging station (CS) infrastructure and its challenges for the Indian scenario. Battery electric vehicles (BEVs) are promising class of drive trains in the coming years especially in urban regions in order to shift the decentralized exhaust emission in megacities to centralized power plants in rural areas. Up to now the ...

Lithium-ion secondary batteries are commonly used in electric vehicles, smart phones, personal digital assistants (PDA), notebooks and electric cars. These lithium-ion secondary batteries must charge and discharge rapidly, causing the interior temperature to rise quickly, raising a safety issue. Over-charging results in an unstable voltage and current, causing potential safety problems, such as...

This paper is the first of a two part study which quantifies the economic and greenhouse performance of conventional, hybrid and fully electric passenger vehicles operating in Australian driving conditions. This first study focuses on the total cost of vehicle ownership. Two vehicle sizes are considered, Class-E and Class-B, which bracket the large majority of passenger vehicles on Australian r...

Plug-in hybrid electric vehicles (PHEVs) enable their drivers to choose whether to use electricity or gasoline, but this fuel flexibility benefit requires the purchase of additional battery capacity relative to most other vehicles. We value the fuel flexibility of PHEVs by representing the purchase of the battery as the purchase of a strip of call options on the price of transportation. We use ...

A sustainable microgrid for supplying power to electric vehicles (EVs) is investigated in this thesis. The energy produced by the microgrid would be directly transferred to the electric vehicles via on-road charging systems. The proposed sustainable microgrid is located on the roadside and consists of wind turbines, solar panels and a stationary storage system. The optimum sizing, the topology ...

This paper describes diffusion of electric vehicles and novel social infrastructure from the viewpoint of systems innovation theory considering both human society aspects and elemental technological aspects. Firstly, fundamentals of the systems innovation theory and the platform theory are mentioned. Secondly, discussion on mobility from the viewpoint of the human-society layer and discussion o...

battery pack is the main energy storage element, and directly affects the performance of electric vehicle. this paper selects the forced air cooling of horizontal battery pack as the study object, and researches the heat dissipation performance of different operating conditions with fleunt software. results indicate that: according to the four kinds of transient state conditions and steady stat...
